The invention relates tothe wrappingof cylindrical packagesand has been developed and practiced principally ,in connection with the wrapping orpackag ing of cylindrical bolts or rolls of textile aiidjother fabric. .Such rolls or boltsof fabricate, in accordance with the present practice, protected by wrapping with sheet niaterial, as p'aper passed about the cylindrical surface of the same as the fabric itself is wrapped in rolling. Theends of the bolh if protected at all, were covered ,with considerable. difiiculty. Further, the bolts when so wrappe d', in. ac.- cordance with previous methods, as to en- :closethejen ds aswefllj as the sides,.cou ld not be mounted on a shaft orpole thrust through the center .of theroll in, accordance with the practice of mounting such boltsrf'or use, as the wrapping completelyelosed the axial ends, and to mount-the bolt .iii this rn'anner itwas necessary toreniove" the wrapping.

The presentinvention relates to a niethod of wrappingcylindrical ,bolts of fabric, and sheet material which may be performed I116 chanicallyl as wellas by hand,andto acylindrical package so wrapped a'njd other bodies p l of mi e et t.

, "heerticle embodying ,inyentio'n'consists of a c'ylindricalbody which inay-befa roll or bolt of sheetniaterial; as fabric wrapped with. a iiarrowpontinuonsstrip of sheet wrapping material, paper or water proof paper, cloth or the like, wound abput the cylindrical body, the strip fabric being placed on the cylinder; in the fo'rin. of a series of loops, each loop I being passed about the I cylinder substantially in the y direction of the intersection ,with the surface thereof or, the line formed by theinterse'ct-ion of the surface thereof with a p lane. parallel to the axis of the cylinder, bilt preferably spaced slightly away from, said axis. The spacing; is .not essential'unless it .is desired to leave, the-ends open at t-hecenters. The successive loops are: placed on the cylindrical surface edge to edge,.or slightly overlap,- ping, and passed across the. endsparallel to thedilferent di arneters thereof, the angle of each loop being varied from the angle of the next preceding loop to provide for the laying of. the successive loop sledge toedge or overlappinglas aforesaid. The

method thiisoutlined in connection with the description ,of' the package is a feature] of bhQvlhYQilliiOh, l

Figure 5 1s a fraginentaryview illustrating the use .of two stripsside byside in wr rpp ngith r ll Referring to the drawings by numerals, eachof which is use d@to indicate the. same or. similar paits in (the different figures, the

package, as shown, comprises a cylindrical body '1, wh 1ch,,1n accordance wit-lithe prefered former tliei'nventionas practiced, is

a cylindrical boltpr roll of-sheet material,

astextile fabric2. Thiseylindii'cal body l is wrapped orfcovered, in accordance vwith the invention, by ',placing the end I ofj-the strip foibthe,oyli'nd'er, preferably on the end as.at. 1-5 ,a-nd th'en winding one or-inore narrowestrips,ofrsheet-niaterial 3, which ispr'e'ferably paper, about the cylinder rorming series of loops, 'e aeh loop being laid substantially on the liiiefforined by the intersection with ,the surface of the cylinder, of a plane parallellto, but preferably spaced slightlyaway f'roni the axis of the cylinder.

It will be noted that the" separate loops l; in which the wrapping strip i'sflaid on the cylinderl overlap sligl' tly at 5. The angle of the respective loops, as shown at the end of the cylinder 6, is changed with eachloop or successive singletiirn ofthe niate-rial aboutv the package; The anglebetween the respective adjacent successive loops or turns 4 is shown as equal to the angle between two radii which are spaced at the periphery of the package by an arc of a length substantially equal to the width of the strip 3 reduced by the overlap 5 ofthe edges on the cylindrical surface.

The spacing of the strip 3, :or more particularly the portions 7 of each loop. which cross the ends of the cylinder, away from the center, produces the central openings 8 in the wrapper at the ends which maybe utilized for insertion of "a pole or shaft on which the bolt of cloth may be mounted for unwrapping, the wrapping beingretained to protect the bolt'until it is used, butthe spacing of the loops and particularly the portions 7 thereof crossing the ends away from the center, as described, is not essential to the practice of the invention; The outside end of the strip 3 at 16 may be fastened side. with a stic in any suitable manner, as by means ofadhesive. a

In'Figures 3 and'4 I have shown a strip of water proof paper which has been found satisfactory and desirable asa wrapping I I means for the package of th'e'invention, producing a substantially waterproof package. The material thus illustrated is a laminated material consisting oftwo strips 10 of paper or the like, each of which is coated on one asphalt compound, the coating being indicated by reference character 11. On this is laid a'coating of cheap fiber 12, as hemp, jute, or the like, there being preferably a layer of this material on each of the layers of sticky material 11. 'The fibers are preferably deposited in two layers 14 and 15 at right angles to each wrapping may other. The strips of paper 10 thus coated on one side with the sticky asphal'tic material 11, and the fibers 12 preferably laid at right angles, as shown at 14: and 15, are placed with the coatedsides in contact and rolled to press the asphalt through thejfibers and cause the two strips to adhere closely. I This material may be manufactured in the form of endless or long webs of considerable width and cut into strips for thepurposes of the present invention. Thepractice of the invention is not intended to be limited to the use oftany particular material in and for the wrapping strips.

The package and method thus described have considerable advantages in that the culty as to leave the axial aperture 9 in the roll open at8 for the admission of a shaft or pole on which the roll or bolt is mounted for use of the material, the wrapping being thus permitted to remain in lace, protecting the material until it is used.

By use of the waterproof wrapping strip described, waterproof, protecting cover is instantaneously applied to the bolt.j

I have thus described specifically and in detail a method and article in accordance with myinvention in order that the nature and manner of practicing the invention may be clearly understood. However, the specific terms herein are useddescriptivehv rather than in 'a limitin sense, the'scope of the invention being defined in the claims; What I claim as new by Letters Patent is:

11. A package comprising a cylindrical body and a wrapping therefor in the form and desire to secure" of strip material extending around the package in a series of loops, each loop encornpassing the entire outside surface of the package and lying thereon in a line which is substantially the intersection. with the cylindrical surface of a plane parallel to the axis, and each loo being at an angle to the succeeding w ereby the wrapping material is cause to contact as to the edge portlons and cover the sides and ends of the cylinder.

2. A packagecomprising a' cylindrical body and a wrapping therefor in the form of strip materialextendi'ng around the ackage in a series of loops, each loop ying thereon in a line which is determined by the intersection with the cylindrical surface of i a plane parallelto the axis, each loop encompassingthe entire outside surface of the package and being at an angle to thesucceeding loop whereby the wra ping material is placed in contactas to the edge portions of the adjacent loops and uniformly distributed over thelsides of the cylinder, the loops being spaced'slightly from the center to leave an opening at the center of each end. r

V 3. A package comprising a roll of fabricand a covering for the same comprising a narrow strip of paper, and asphaltic material and fibercovered by the aper stri s,

thewrapping material being aced on t e roll in the form of a series 0 overlapping loops each loop encompassing the entireoutside surface of the package and crossing the curved sides of the roll in a direction parallel to the axis andcrossing the ends, the

angle of each loop being different fromthe angle of the preceding loop, so that the material covers the entire surfaceof the package and isuniformly distributed over the curved sides of theroll 4; A package comprising a body and a covering for the same in theform of narrow strip material, the Wrapping material being placed on' the body in the form of a series of overlapping loops, each loop encompassing the entire outside surface of the package and crossing the sides of the body in a direction parallel to the axis and crossing the ends, the angle of each loop being difierent from the angle of the preceding loop, so

that the material covers the-entire surface of the package and is uniformly distributed 10 over the sides of the body.
